U.S. Rep. Michele Bachmann (R-Minn.) says it's "insulting" that Fox News host Chris Wallace asked her if she's a "flake" when she appeared on his program on Sunday morning.

Wallace apologized for the question in a web video after he interviewed the presidential hopeful.

“A lot of you were more than perturbed, you were upset and felt that I had been rude to her," says Wallace in the clip posted online. "And since in the end it’s really all about the answers, and not about the questions, I messed up, I’m sorry. I didn’t mean any disrespect.”

Asked if she accepts the apology by ABC News' Jon Karl, Bachmann said, "I think that it's insulting to insinuate that a candidate for president is less than serious. I'm a very serious individual." When pressed on the matter further she said, "Those are the small issues. I'm focused on the big ones."
